What is Bio Carb Soil Amendment?

GS Plant Foods Bio Carb is a high-impact, carbon-rich organic soil amendment made from ancient, biologically active humate deposits. This natural soil booster revitalizes depleted soils, stimulates microbial activity, and maximizes nutrient uptake — giving you healthier plants, thicker lawns, and bigger harvests. Bio Carb works for home gardens, turf, potted plants, and large-scale farms, turning sandy or nutrient-poor soil into a thriving, fertile ecosystem — no synthetic chemicals needed.

If you want to maximize pasture growth, improve soil health, and support healthier livestock, GS Plant Foods Hay & Pasture Formula is the ideal solution for creating lush, nutrient-rich grazing fields.

 Key Benefits of Bio Carb Organic Soil Amendment

  • 🌱 Carbon Boost for Soil Health — Replenishes depleted soil with ancient organic carbon, restoring structure, fertility, and long-term productivity.
  • 🦠 Microbial Activity Stimulator — Feeds beneficial soil microbes to improve nutrient cycling, root health, and disease resistance.
  • 💪 Nutrient Efficiency & Uptake — Enhances absorption of macro- and micronutrients for faster, more vigorous plant growth.
  • 🌍 Certified Organic & Eco-Safe — Naturally mined, chemical-free, and safe for all plants, pollinators, and soil life.
  • 🏡 Versatile for Any Application — Ideal for lawns, vegetable gardens, container plants, and acreage farming.

Bio Carb Ingredients & What They Do

  • Ancient Humate (Humic Acid) — Low molecular weight humic acid for rapid soil penetration, nutrient chelation, and improved cation exchange capacity (CEC).
  • High-Density Organic Carbon — Rebuilds soil organic matter, improves water retention in sandy soils, and reduces compaction.
  • Beneficial Soil Microbes — Boosts populations of soil-friendly bacteria and fungi for a living, self-sustaining root zone.

How to Use Bio Carb — Application Rates & Instructions

Simple Application for Maximum Results:

  • Turf, Trees & Shrubs: 1 lb per 100 sq ft — spread evenly and water in.
  • Vegetable & Flower Gardens: 1–2 lbs per 100 sq ft — broadcast and till into top 2–3 inches of soil.
  • Potted Plants:
    • Small pots (6") — 1 tbsp mixed into potting soil.
    • Large containers — ¼ cup per gallon of soil.
  • Pasture & Acreage: 200–400 lbs per acre for maximum soil restoration.

For best results, apply at the start of the growing season and supplement monthly throughout the season.

What Our Customers Are Saying

Thank you so much for Orchid Love. I bought mine on Amazon.com. I have been using it for the last five months. My orchids haven't looked better. Then I discovered a secret using your Orchid food. I have been dripping it down the old spikes of my 14 orchids not in flower for the last month. Now I have 5 of my orchids sending up new spikes that should be blooming around Christmas and 3 shooting secondary spikes off the old spikes. Even my other house plants love it. Thank you so much.

I received this product in a very timely manner. After the first application this seems to be working on my fall garden in zone 7. The lettuce, cauliflower, and broccoli all responded to a foliar spray of 1 Tbsp mixed in a half gallon of water. I also applied it to my tomato plants that had slowed down due to the colder weather and was surprised to see all of the plants start setting new blooms and fruit. I was at the point of actually pulling the tomato plants out for the year but look to maybe get a few more tomato's off each plant now!

Hi, just received your kelp and humic acid per Amazon.I scoped them at 40 and 100x shortly after opening and could not believe the diversity compared to a competitor's similar products.I provide the most thorough organic lawn/soil treatments in the Gainesville Fl area, and looking forward to continuing business."Thanks for your product

— Chad Freeman

So far, my plants and microgreens seem to respond well--new growth and deeper color--to the spray I mixed with water and store in the refrigerator.
My only complaint is that the bottle could be designed better so that the liquid doesn't drip everywhere and get a little messy even when using a funnel to catch extra liquid.
It smells strong & stains, so prepare your mixture outside or on a plastic covered table.

FAQs

Please read our FAQs page to find out more.

Why do organic fertilizers like yours have lower NPK values than synthetic fertilizers?

Synthetic fertilizers artificially spike NPK levels far beyond natural amounts, much like vitamin pills overload the body with nutrients it can’t fully absorb. Organic fertilizers, however, workwithnature—enhancing plants’ ability to uptake nutrients efficiently without excess runoff. This means lower NPK numbers deliverhigher effectivenesswhile protecting ecosystems from pollution caused by synthetic waste.

How should I store your products to maximize shelf life?

Store products in a cool, dry place away from direct sunlight and extreme temperatures. Ensure lids are tightly sealed after use. While most formulas have an indefinite shelf life, always mix only what you need for immediate use to maintain potency.

Do I need to water my lawn after applying your liquid fertilizers?

No watering is required! Our liquid formulas absorb quickly into the soil. For best results, apply early in the morning to allow 2-3 hours of soaking time before rain or irrigation. This ensures maximum nutrient retention without runoff.

Is it safe to harvest vegetables right after using your products?

Yes! Most of our products have a zero-harvest interval, meaning you can pick produce immediately. However, we recommend waiting 2-3 days after application for optimal nutrient absorption and flavor development.

How do organic fertilizers reduce environmental harm compared to synthetics?

Synthetic fertilizers overload plants with nutrients they can’t fully absorb, leading to harmful runoff that pollutes waterways. Organic formulas, like ours, mimic nature—delivering balanced, bioavailable nutrients that plants use efficiently. Think of it as feeding your garden a wholesome meal instead of forcing it to “overeat” synthetic additives.
